The transatlantic APRS balloon attempt (PBH10) will use the callsign of KC2TUA-10 with an anticipated launch window 8-11 PM EDT Wednesday April 29th. The anticipated flight path from Oswego, NY is northeast through New England, Nova Scotia, Newfoundland, Greenland, and Iceland on to Europe.
The balloon will have both a an APRS beacon operating at 144.800 (To maximize the potential for reception in Europe the balloon will operate on the European frequency) and a 40 meter CW beacon on HF at 7.102.55MHz (+/-100Hz). To track the early part of the track, APRS operators throughout the flight path are asked to tune their receivers to the 144.800 frequency and to activate their stations as WIDE1-1 digipeaters or as IGates so that the packets are digipeated over onto the USA frequency while the balloon is over the USA and Canada in order to provide tracking.
